agree with lozzo on this subject
Cars stopping is traction limited, they can brake until the front wheels lock.
Bikes stopping is generally chassis limited, you will do a stoppie while only utilising half of the available grip.

That's the physics behind it, I could show you some sums but even with far better tyres on the bike the car will still stop sooner.

I'd like that too

Ok, the point I wasnt trying to make was which is better at stopping car vs bike. It was technology has moved on, therefore speed limits should too.

Mr Clarkson demostrates it a bit better here - jump to 1:50

If you take out reaction times (and the SLR stopped with some to spare to account for this)

It is as safe driving a SLR at 120 than it is driving a 1960 Ford Anglia (which I believe the stopping distances are based on) at 60 mph.

I can't honestly think of one time I've happily sat at 70mph on a motorway for anything longer than a mile or so without getting bored and upping the speed.
Agree with Lozzo on this.

80 Mph is ze EU sticking ze oar in, with harmonisation the next thing is well be driving on the right and have the Denmark luxury tax

You up the limit to 80 people will do 90 like everyone does (me included) with 70 mph.

I like the camera name 'n' shame tho, shame the DVLA wouldn't allow peoples names to be shown :rolleyes:

Show any name you like, the people behind on the motorway won't know any different.

Yeh,lets have a better class of accident by going faster,after all we all seem to be surviving the copious amount we have on here at the slow speed we are allowed currently.Have I completely lost it or is there another thread running about fuel economy and you all want to go faster,sudden increase in wages or mental block?
This has to be the most contradictory forum in existence.
Foreign motorways are a lot less busy than ours and the general volume of traffic in Western Europe less apart from cities which are much the same

If we had better driving standards than we currently have the problem would be partially resolved,more than changing the speed limits will

As everything on top gear is fake, id take it with a bag of salt :mrgreen: but im sure the principle is right.

I dunno... I think most people travel at the speed that feels about right, rather than the speed they think they can get away with. My car trundles along nicely at 80, at 90 it feels like it's working a wee bit too hard, at 100 it feels like it's about to implode. Put the limit to 80 and I'll still motorway bash at 80 and economy cruise at 60. Seems to be the old 85th percentile thing at work rather than "Oh better not go more than 10mph over"

Feels right? Its different for every car. I think its precisely what they think they will get away with :mrgreen:

Meanwhile, in Spain:

THE government has decided to reduce the speed limit on dual carriageways to 110kph to help people save petrol. The law, which was announced by the Government Vice-president and Interior Minister, Alfredo Perez Rubalcaba, will come into effect on March 7, and has been announced as a provisional measure, although no mention was made of when it might be lifted.
The government claims the sole purpose of reducing the speed limit from 120kph to 110kph is to help people survive the constant rises in petrol prices, mainly due to the situation in Libya.
Meanwhile, Renfe will reduce the price of medium and short distance train tickets to encourage people to use trains
Alfredo Perez Chupacabra?!
